If you're looking for a good Star Fox TG story I'd recommend this one:
http://www.fanfiction.net/s/4237416/1/Something_Blue and its sequel
http://www.fanfiction.net/s/4825598/...The_Other_Life . The first one has a very slow and pretty in depth transformation. Its for the most part well written and I'd recommend it highly. Its not overly explicit though...so don't go into it expecting that.
